var basket = {
        var self = this;
    };
    basket.arr = [];

    basket.add = function() {
        $('.quantity').on('keyup', function(){
            var id = $(this).attr('data-id');
            var name = $(this).attr('data-name');
            var img = $(this).attr('data-img');
            var quantity = $(this).val();



            $('.quantity').each(function(){
                if($(this).val() > 0) {
                    var id = $(this).attr('data-id');
                    var name = $(this).attr('data-name');
                    var img = $(this).attr('data-img');
                    var quantity = $(this).val();

                    console.log(this.arr);
                    this.arr.push([id, name, img, quantity]);

                }
            })

            $('#basket_title').nextAll().remove();

            for(var i = 0; i < arr.length; i++) {
                $('#basket_title').after('<div style="float:left"><input class="id_basket" type="hidden" value="' + arr[i][0] + '"><img style="width:60px" src="img/upload/' + arr[i][2] + '"><span>' + arr[i][1] + '<input style="width:40px" type="number" min="0" value="' + arr[i][3] + '"><img class="delete" style="width:25px" src="img/upload/delete.png"></div>');

    }
